CLIO B. YAW, OF NEW YORK, N. Y., ASSIGNOR TO WYCKOFF, SEAT/[ANS & BENEDICT, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented May 28,1912.

-To all whom it may concern Be it known that I, CLIo B. Yaw, a citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to paper feeding mechanism for typewriting machines and has for its main object to provide an improved paper clamp or holder which is especially adapted to labels and other small work sheets.

To the above and other ends the invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

One form of my invention is illustrated in the accompanying drawings wherein Figure 1 is an enlarged front to rear vertical sectional view of a platen and platen carriage showing also the upper part of the machine on which the platen carriage is mounted, my invention being shown in place on the platen, the section being taken just at the right of the left-hand side bar of the platen frame. Fig. 2 is an enlarged fragmentary top plan view of the platen and platen frame showing the devices of my invention in place on said platen and also showing a paper finger on the platen carriage. Fig. 3 is an enlarged fragmentary front view, partly in section, showing the platen and the paper clamp thereon as the latter appears when moved to inoperative position. Fig. 4. is an enlarged longitudinal sectional view taken centrally of the platen and showing the left-hand side portion of the platen with my improved paper clamp in place thereon. Fig. 5 is an enlarged fragmentary perspective view of a part of the paper clamp, said part being hereinafter termed a clamp carrier. Fig. 6 is an enlarged perspective view of another part of the paper clamp, said other part being hereinafter termed a clamp support. Fig.7 is an enlarged perspective view of a releasing member which operates to release the paper clamp or render it inoperative.

lVhile I have shown the devices of my invention applied to a No. 6 Remington machine it should be understood that they may be applied to other styles of typewriting machines.

In the drawings, 1 designates the top plate of the machine from which rise standards 2 supporting a back rail 3. Supported and guided on the rail 3 are rollers 4 mounted in a carriage truck 5 on which is pivotally supported a platen frame comprising a rear bar or rod 6, side bars 7 and a front bar 8. Mounted on the front bar is a wheel 9 which cooperates with a shift rail 10 carried on arms 11 which are pivotally supported on the main frame of the machine in the usual way. The parts above briefly described are found in the ordinary Remington typewritng machine and it is deemed unnecessary to describe them at greater length. The platen comprising the usual wooden core 12 and an inclosing rubber sheath 13 is rotatably mounted in the platen frame. Said platen is provided at the left hand with a platenhead 14 which,

as clearly shown in Fig. 4, is secured to the platen by wood screws 15 and has a central boss or hub 16, the latter being perforated to receive a short axle or shaft 17. The shaft is secured in the hub by a set screw 18 and passes outwardly through a bearing opening in the left-hand side bar 7 of the platen frame, said shaft at its outer end carrying the usual finger wheel 19. It will be understood that the right-hand end of the platen is provided with a platen head which is or may be of the usual construction; and that at the right the platen has a spindle or axle bearing in the right-hand side bar 7 of the platen frame.

My novel paper clamping device or paper clamp is adapted to be supported on the boss or hub 16 and to be secured or clamped against the outer face of the platen head 14 by a device presently to be described.

The main parts of the paper clamp or holder are shown in detail in Figs. 5, 6 and 7. The clamp comprises a clamp support shown in Fig. 6, said clamp support being formed preferably of-a single piece of metal and comprising a platelike body portion 20 and a hub 21. The clamp support is formed with a slot or cut-away 22 which enables-the support to straddle and fit down over the hub 16 of the platen head, and the hub 21 of said clamp support is countersunk, as indicated at 23, to cooperate with a securing device presently to be described. The sides of the hub 21 are formed with oppositcly disposed bearing openings 24 which receive the reduced cylindrical bearing ends 25 of shouldered pivot screws 26, said screws engaging tapped holes 27 formed in the sides of the body portion 28 of a clamp car rier, the latter being shown in detail in Fig. 5 and the screws 26 being clearly shown in cooperation with both the clamp support and the clamp carrier in Fig. 1. The body portion of the clamp carrier is formed with a central circular opening 29 which fits over the hub 21 of the support and the lower portion of the carrier is cut away as indicated at 30 providing a mouth for the opening 29 and enabling said carrier to be passed down over the hub 16 of the platen head. At the upper part of the body of the clamp carrier is an arcuate flange 31 and immediately beneath the flange the body portion 28 is cut away to form an arcuate groove 32. The outer edge of the flange 31 is provided with an upstanding or outwardly projecting rib 33. Supported on the flange 31 and abutting against the rib 33 are a pair of fingerlike clamping or gripping members 34, the shape of which is best shown in Figs. 2 and 3. Each of the members 34 is curved in cross-section so as to conform to the curvature of the platen against which they are adapted to bear. These members or fingers are formed preferably of sheet metal and at their securing ends are provided with angular extensions 35 which conform to the shape of the flange 31 on which they are supported. The clamping fingers 34 are each secured in place on the clamp carrier by headed screws 36 which pass through suitable openings in the outer ends of the clamping finger and through an elongated slot 37 in the flange 31 and then engage with threaded openings in a clamping block 38 which is received in the groove 32 and abuts the under side of the flange 31. The arrangement just described is clearly shown in Fig. 5. It will be understood that when the screws 36 are tightened they serve to draw the associate clamping block 38 up against the under side of the flange 31 and thereby to frictionally secure the associate finger 34 in a fixed relation with the clamp carrier. By loosening the screws 36 the associate fingers 34 are freed so that they may be moved bodily toward each other on the flange 31 until the parts 35 contact and away from each other as far as the slots 37 in said flange permit. The ends of the clamping fingers 34 abut the rib 33 and are held by said rib from pivotal movement on the flange 31. Between the fingers 34 and below the flange 31 (as shown in Figs. 4 and 5) the clamp carrier is provided with a rectangular opening or slot 39 which receives a releasing member or device 40 shown in de than the width of the slot 39 so that said pin may cooperate with the bottom and side of the groove 32 at the sides of the slot '39. The inner face 40 of the releasing member cooperates with the outer face of the body portion 20 of the clamp support in a manner present-1y to be described when said releasing member is actuated by a handle or finger portion 40 which projects outwardly through the slot 39 so that it may be conveniently grasped by the operator. The arrangement of the releasing member with its fulcrum pin 41 inclosed between the clamp support and the clamp carrier is clearly shown in Figs. 3 and 4. The clamp carrier is pivotally mounted on the clamp support by the pivotal screws 26 as previously described and is normally maintained with the inner face of the body portion 23 pressed against the outer face of the body portion 20 of the clamp support by a pair of short coiled springs 42. The arrangement of these springs will be understood from a consideration of Figs. 1, 4, 5 and 6.. Each spring has one of its ends seated in a depression 43 formed in the outer face of the body portion 20 of the clamp support, the

depressions 43 being arranged one at each side of the cut-away 22 and at the underside of the hub 21 as the parts appear in the drawings. The other end of each spring 42 is seated in a corresponding depression 44 formed in the inner face of a finger-like part 28 which extends from the body 28 of the clamp carrier at the sides of the opening 30, the parts 23 forming the lowerportion of the circular opening 29 in the clamp carrier. As shown in Fig. 4 the inner faces of the finger-like parts 28 or those faces which are opposite the clamp support are beveled or inclined so that normally a V-shaped space or slot 45 exists at each side between the clamp support and the clamp carrier below the pivot screws 26.

When the parts of the paper clamp (comprising the clamp support, the clamp carrier pivoted thereon, the clamping or gripping fingers 34 adjustably secured on said clamp carrier and the releasing device 40) have been properly assembled, the paper clamp as a Whole may be detachably secured on the hub 16 of the platen head 14 as will now be described. The hub 16 is exteriorly threaded for the greater part of its length as shown in Fig. 4 and receives a clamping nut 46 having a knurled finger portion or head 47 by which the nut may be readily turned and thereby moved back and forth along the hub 16. When screwed or turned forwardly the nut is adapted to move rightward along the hub and its inner end portion is adapted to enter the countersink 23 in the clamp support. To secure the paper clamp as a whole in place on the platen said paper clamp is passed down over the hub 16 and the clamping or thumb nut 46 is then turned forwardly as far as possible, thereby forcing the body portion 20 of the clamp support tightly against the exterior face of the platen head 14.

It will be understood that prior to tightening the thumb nut 46 the paper clamp may be arranged at any point circumferentially of the platen and of the hub 16 but that after said thumb nut has been tightened the clamp as a whole will be maintained in a fixed relation with the platen and will be rotated as the platen is rotated. It will further be understood that the inner end portion of the thumb nut 46 fits snugly in the countersink 23 when the nut 46 is screwed up tight as shown in Fig. 4 and that this arrangement prevents accidental displacement of the clamp as a whole radially of the platen. The outer or left hand face of the head 47 of the thumb nut is formed with a circular groove 48 (Figs. 1 and 4) which groove gradually increases in depth from its beginning 48 to its end 48 which latter, as clearly shown in Fig. 1, is only a short distance from the beginning 48 The closed end 48 of the groove is adapted to cooperate with a stop which, in the present instance, is shown in the form of a set screw 49 which projects from the hub 16 slightly to the right of the left-hand side bar 7 andis shouldered off to provide a flat inner face 49 as shown in Fig. 4.

lVhile the thumb nut may be turned on the hub 17 to release or free the paper clamp said nut is prevented from being 10V6Cl far enough leftward to engagewit-h the inner side of the lefthand bar 7 and thereby bind the parts so as to prevent turning movements of the platen, this prevention being caused by the cooperation between the end 48 of the groove 48 with the forward side of the screw stop 49. The cut-away portion of the screw stop 49 permits the thumb nut to be turned so as to cause the groove 48 to pass over and partly embrace the top and right-hand side 49 of the screw stop but before the bottom of the groove can contact with and bind against the flat face 49*, the end 48 of said groove will contact with the forward side of the screw stop 49 to prevent further turning movement of the nut 46 in one direction.

It will be understood that any other suitable means may be employed for preventisg a binding of the nut 46 against the platen frame.

My invention is particularly adapted for use with small work sheets such as the circular label illustrated in the drawings and designated by the reference character a. In employing said invention with a label like a the clamping or gripping fingers 34 are first adjusted or spaced apart as has been described until they are in their proper relation for holding the top and bottom edge portions of the label (4 against the platen. Assuming then that the paper clamp has been secured in place at the lefthand end of the platen by means of the clamping nut, the operator first preferably turns the platen until the paper clamp is uppermost as shown in Figs. 1 and 4 of the drawings and then presses down on the finger portion 40 of the releasing member 40. This causes said releasing member to fulcrum on its fulcrum pin 41, the latter bearing against the bottom and side of the groove 32 on the clamp carrier, with the result that the face 40 of said releasing member will be pressed against the outer face of the body portion 20 of the clamp support. As the finger piece 40 is pressed downwardly the result of this action of the member 40 will be to overcome the springs 42 and swing the lower portion or arms 28 of the clamp carrier toward the outer face of the clamp support about the pivot screws 26 and to swing the upper part of said clamp carrier away from the clamp support about the pivot screws, at the same time lifting the clamping or gripping fingers 34 upwardly and outwardly away from the surface of the platen. This pivotal movement of one part of the paper clamp on another part takes place about a pivotal axis at right angles to the platen axis and is permitted by reason of the slots or V shaped openings 45 normally existing between the clamp carrier and clamp support below the pivot screws 26. Said pivota movement it will be understood will be continued until the gripping fingers 34 have 1 been swung away from the platen to the positions shown in Fig. 3 at which time it will be noted the V-shaped openings or slots 45 have been nearly closed and the springs 42 have been greatly compressed.

The gripping fingers 34 are preferably formed of spring metal and when in inoperative position as shown in Fig. 3 the inner or free ends of said fingers are preferably slightly inclined toward each other as shown by the dotted lines in Fig. 2. Holding the paper clamp open or in released position as shown in Fig. 3 with one hand, the operator may next place one of the labels a on the platen with the other hand and in position to be clamped by the fingers 34 when the finger piece 40 is released and the rotary parts of the clamp are restored to operative position by the springs 42. During the return movement of these parts to operative position the gripping" fingers will contact with the top and bottom edge portions of the label a and will clamp said label tightly against the platen. The arrangement is such, however, that before the parts of the clamp are finally arrested the springs 42 will act to force the fingers 34 against the platen with sufficient force to overcome the inherent spring of the fingers so as to slightly spread the inner ends of said fingers apart until when the final arrest of the parts takes place said inner ends will be substantially parallel as shown by the full lines in Fig. 2. This spreading of the paper fingers is possible because of the inherent give or yield in the metal of which said fingers are made and is a valuable feature as it automatically spreads the portion of the work sheet or label a between said fingers with the result that the working portion is held tightly against the platen and any tendency to bulge or stand away from the platen is obviated and wrinkles will be smoothed out. The platen may now be turned by the operator in the usual manner until the label a is in position for enabling the first line thereon to be written.

Preferably one of the usual paper fingers 50 which is slidably mounted on the front bar 8 of the platen frame is used to facilitate the proper positioning of the label for writing. Said paper finger may be slid leftward along the front bar 8 until in the position shown in Fig. 2 just to the left of the edge of the label a. The clamping fingers on the latter are so thin and hug the platen so closely that they readily slide over the inner face of the paper finger 50 without obstructing the turning movements of the platen, nor will the other usual paper feeding and controlling devices and the usual platen scale obstruct said turning movements. The paper finger 50 is scored or cut as indicated at 51 to correspond with the writing line on the platen and when the platen carrier is lifted to expose the printing point on the platen the latter may of course be readily turned until the proper point for commencing writing 'on the label a is opposite the line indicator 51 on the paper finger 50. From an inspection of Fig. 2 it will be apparent that as the writing takes place the gripping fingers will hold the label on opposite sides of the writing or printing line and that they are substantially parallel with the direction of letter feed. After the label or work sheet a has been printed the platen may be turned and the label may be released by pressing down on the finger piece 40 and another label may be clamped in place as has been described above.

If preferred the paper finger 50 may, of course, be slid rightward on the platen frame so as to be out of the path of the clamping or gripping fingers 3 1- and instead of turning the platen until the gripping fingers are at the top side thereof as shown in the drawings, the platen frame may be lifted to expose the writing after the label has been filled in, and then the gripping fingers may be released, the finished label removed and a fresh label inserted before the platen frame is swung down to resume writing. Or, if preferred, this method may be employed even when the paper finger 5O overlaps the grippingv fingers 34 as shown in Fig. 2,

although in such case additional pressure must be applied to force said paper finger away from the platen as the gripping fingers are swung away therefrom.

It will be seen that I provide a paper clamp or clamping contrivance of novel construction and which is very simple and efficient in operation; that said paper clamp may be readily arranged in place and as readily detached by the manipulation of the clamping nut 46; that said paper clamp is arranged at one side of the platen only; that the gripping fingers 84 extend lengthwise of the platen only part way along the platen and on opposite sides of and substantially parallel with the printing line when the writing takes place; that the gripping fingers are arranged substantially parallel with the direction of letter feed movements of the platen; that when in working positionsaid fingers hold or clamp only the upper and lower portions of the label; that when the paper clamp is released the parts moved for this purpose (said parts comprising the clamp carrier and the clamping fingers, are given rotary movements about a pivotal axis on the stationary part of the clamp, which part has been called the clamp support, said pivotal axis being at right angles to the platen axis; and that during the rotary movements of the clamping fingers toward and away from the platen, said fingers, by reason in this instance of their inherent sprin'giness, also are capable of a limited relative movement toward and away from each other, enabling the work sheet to be spread or smoothed out and caused to lie closely and snugly against the platen so that any tendency to wrinkle or bulge is obviated.

It will further be noted that I provide a paper clamp or paper clamping contrivance comprising a pair of gripping fingers which are relatively adjustable toward and away from each other and which also when brought into cooperation with the platen are adapted to be spread slightly apart and to be put under tension. This spreading action is due in the present instance to the fact that the platen is rounded or circular and exerts a wedging effect on the gripping fingers or, as they may be termed, gripping or clamping devices, when they are forced against the circular platen by their actuating spring or springs.

It will be understood that changes of various kinds may be made without departing from my invention.
